Cultivar'Aurea'
OriginVermont, US

The American elm cultivar Ulmus americana 'Aurea' was cloned from a tree discovered by F. L. Temple in Vermont at the end of the 19th century.[1][2]

Description

The tree was described simply as having yellow foliage.

Pests and diseases

No specific information available, but the species as a whole is highly susceptible to Dutch Elm Disease and Elm Yellows; it is also moderately preferred for feeding and reproduction by the adult Elm Leaf Beetle Xanthogaleruca luteola,[3] and highly preferred for feeding by the Japanese Beetle Popillia japonica [4][5] in the United States. U. americana is also the most susceptible of all the elms to verticillium wilt.[6]

Cultivation

Young trees are grown in Belgium and London, cloned from a tree (now dead) which grew in Illinois.
